Popis: The highfin blenny, Lupinoblennius nicholsi, is a marine fish species reported in reef and rocky inshore habitats with a disjunct distribution in the southern Gulf of Mexico. Overall, there are very few studies on this species and there is a scarcity of molecular resources for genetic comparisons. We set out to report the first mitochondrial genome for L. nicholsi and report a range expansion for the species. An individual of L. nicholsi was collected from the coast of Dauphin Island, Alabama. The mitochondrial genome was sequenced, assembled, and annotated. The fragment corresponding to cytochrome oxidase I (COI) was used to compare this sample to other cryptobenthic species of the Atlantic. Finding a mature individual in the coast of Alabama implies this species has a continuous distribution throughout the northern Gulf of Mexico. The mitochondrial genome of L. nicholsi is 16,416 bp in length and comprised of 13 protein coding genes, 22 transfer RNA genes, two ribosomal RNA genes, and a non-coding D-loop. Comparisons using COI support the species is L. nicholsi and separate it from other cryptobenthic fishes found in the area. This study represents the first mitochondrial genome for this L. nicholsi, serving as a reference for future comparative studies with marine fishes. By reporting the range expansion of this species, this study provides insights on the fish diversity of the Gulf of Mexico.
